(defun org-export-region-as-html (beg end &optional body-only buffer)
  "Convert region from BEG to END in org-mode buffer to HTML.
If prefix arg BODY-ONLY is set, omit file header, footer, and table of
contents, and only produce the region of converted text, useful for
cut-and-paste operations.
If BUFFER is a buffer or a string, use/create that buffer as a target
of the converted HTML.  If BUFFER is the symbol `string', return the
produced HTML as a string and leave not buffer behind.  For example,
a Lisp program could call this function in the following way:

  (setq html (org-export-region-as-html beg end t 'string))

When called interactively, the output buffer is selected, and shown
in a window.  A non-interactive call will only return the buffer."
